Taxonomy

The family was originally defined by English mycologist E.J.H. Corner in 1970[3] and revised in 1985 by Jacques Berthier[4] but neither author anticipated the application to a molecularly defined group of agarics first identified by Moncalvo and others in 2002.[5]Molecular studies placed Physalacria, formerly the sole genus in this family, together with the agaric genera Flammulina and Xerula and Armillaria.[5][6][7][8]
